Yup, rand is zero inclusive.

For rounding, you have several options:

• int, which returns the integer portion of an expression. This is probably not what you're looking for, though.
• sprintf, which lets you format your number exactly the way you like it. Remember, there's no real difference betwen string and number variables in perl.
• POSIX::ceil or POSIX::floor, which are the equivalent of ceil and floor in C.
